A German finance court in September questioned the constitutionality of a controversial tax on fuel used in nuclear power plants, a decision that could influence rulings in various finance courts around the country that are reviewing complaints by nuclear operators regarding the levy.

Procrustes the metal worker—not to be confused with Krusty the Klown—was an important figure in Greek mythology. A son of Poseidon, Procrustes was an iron smith, thief, murderer, and inn keeper. He offered hospitality to strangers passing his place on the sacred byway between Athens and Eleusis. For a price.

The International Thermonuclear Experimental Reactor (ITER) in southern France, the world’s biggest nuclear fusion research project, is seeing a revival. After a budget shortfall last year and cost projections that continue to escalate, in September, the project got the European Parliament’s (EP’s) backing for an autonomous budget that seeks to guarantee transparent and reliable financing while limiting cost overruns. Japan also announced that it would increase its budget for ITER by 50% (the current ITER director-general is Japanese). Also in September, scientists announced that after an 18-month shutdown to upgrade the Joint European Torus (JET)—the world’s largest magnetic fusion device—the machine is ready to test materials to be used inside ITER (Figure 5).

As less is heard about the promise of new nuclear reactors in the U.S., more is being heard about the problems of the geriatric atomic set.

Wärtsilä to Provide Rwanda with Engines for Lake Methane Power. Wärtsilä on Sept. 30 said it was awarded a contract by KivuWatt, a subsidiary of the New York–based international power company ContourGlobal, to supply a power plant to the Republic of Rwanda. The turnkey project is of particular significance because the power plant will utilize […]

The operating environment within a condenser is extremely harsh, and in spite of the designer’s best intentions, sometimes tubes made of the best materials fail. The most important tube failure mechanisms typically result from different forms of corrosion and erosion. When it’s time to select new condenser tube material, you’ll need to consider the projected operating environment and failure mechanisms that material will be subjected to.

Public power utilities depend upon access to capital at favorable rates. So the munis pay special attention when Wall Street rating agencies talk about tinkering with how they establish bond ratings for municipal utility projects. Thus, recent moves by Moody’s Investors Service has drawn some fire from public power.

For seven years in a row, the number of new nuclear construction starts increased markedly. Then the accident at Japan’s Fukushima Daiichi plant occurred, prompting shutdowns of existing plants and a rethinking of future plans in many countries. Nevertheless, the International Atomic Energy Agency (IAEA) expects “continuous and significant growth” in the use of nuclear […]

Once the condenser tubes are designed, selected, and purchased, the final step in a retubing project is to remove the old tubes and install the new ones. The success of this project is very dependent upon attending to quality control, following proper procedures, using the right tools, and having a highly skilled workforce.

Losses attributed to condenser tube leaks, fouling, and failures continue to climb, costing the power generation industry an estimated half-billion dollars annually in maintenance costs and loss of production. Investing in an effective condenser maintenance program will reduce those expenses in short order.

Understanding the reliability and failure mechanisms of photovoltaic modules is crucial to understanding how well they will perform over time. But today there are no test standards in place to judge this crucial issue.

In the May issue, we discussed the importance of either preventing copper plating of the high-pressure (HP) steam turbine rotor or finding a good foam or mechanical removal means of restoring lost efficiency. In that article we noted that “copper deposits typically form on the stationary nozzle block or first-stage stationary blades” and that those deposits usually result in a steam turbine loss of capacity at a rate of about 2 to 3 MW per month. We also stated that the “general rule of thumb is that there is a reduction of about 1 MW of generating capacity for each 1 to 2 pounds of deposit that accumulates on the HP turbine.

In the past few years, nuclear concerns, rising oil prices, and a growing understanding of our environmental impact has given energy issues a higher profile worldwide. In this report on the Continental Nordic countries, we look at the efforts being made in much of the Nordic region to secure a sustainable energy supply for the future and at the extent to which the innovative solutions of these countries can be exported around the globe.

Cloud computing is a growing phenomenon for many businesses, large and small, promising significant efficiencies and cost savings. But, as with anything new, computing in the cloud poses some unforeseen legal issues.

This is the fourth in a series of predictive maintenance (PdM) articles that began in the April “Focus on O&M” with an introduction to PdM as a process whereby maintenance is performed based on the condition of the equipment rather than on a predetermined interval. In the May and July issues, we began exploring specific PdM techniques, such as motor-current signature analysis and oil analysis.

One of the great successes of the power generation industry over the past two decades has been the significant increase in nuclear plant reliability and other performance standards. However, there is reason to be concerned that the design, operation, and maintenance practices used by the current fleet of plants do not leverage all the possible advantages from a digital controls upgrade. Perhaps past success is the biggest barrier to future success.

Social media are transforming the world around us, and not just the world of our family and friends. Understanding how the new tools of social interaction impact the job is part of the role of today’s effective manager.

Water has long been energy production’s silent partner. In the past, we Americans seemed to take it for granted that plentiful water supplies would be available for a variety of energy needs ranging from the operations of coal-fired power plants to natural gas production activities.

TVA completed the $1.9 billion restart of the 1,100-MW Browns Ferry Unit 1 in 2007. That restart project provided the opportunity to incorporate state-of-the-art materials and radiation-reduction techniques to ensure that Unit 1 would be an industry-leading low-ALARA-exposure plant when it returned to service. The reductions achieved were significant.

Have you seen too many eyes-glazed-over expressions betraying a lack of interest at your employee meetings? Getting folks to pay attention at meetings is important, and there are ways to make it happen.

The global nuclear industry is moving forward at a brisk pace, only slightly slowed by the Fukushima Daiichi accident. The International Atomic Energy Agency’s most realistic estimate is that 90 new nuclear plants will enter service by 2030. Ten new nuclear plants went online over the past two years. We profile four of them as POWER’s nuclear Top Plants for 2011.

In our September article about the global profusion of natural gas, we based a portion of our discussion on the latest, vastly increased natural gas reserve estimates reported by the U.S. Energy Information Administration (EIA). Since our article was published, the EIA has adjusted its estimates downward. We want you to be aware of those lower recoverable reserve estimates. We also want you to know that the conclusions reached in that article do not change with the new estimates of natural gas reserves.

In many quarters, nuclear power generates enthusiasm. A single pound of reactor-grade uranium oxide produces as much electricity as 16,000-plus pounds of coal—enough to meet the needs of the average U.S. household for more than one year. And whereas burning coal emits carbon dioxide, sulfur dioxide, and nitrogen oxides, nuclear power generation is virtually emissions […]

Selecting the most economical tube for a new condenser, or the retrofit of an existing one, is much more complex than mere price shopping. Each material has unique performance characteristics that affect the operating economics of the entire plant. A case study illustrates the importance of carefully choosing the tube material that is right for your plant.
